Hey Bryce,
I use these, primarily for ice fishing:

No boot is perfect, and those above I find somewhat heavy but my feet stay toasty warm and dry on the ice. I use the Mukluks icefishing on the days where the temp falls within -6 to 0, anything below that or where there's pooled water/slush on the ice I use the Sorrels. I generally walk out on the ice and cover between 2-5 km per day, so the heavier boots are a drawback there. But standing jigging over a hole for an hour or more with windchills breaching -30 these boots do me fine.
Those higher-end mukluks (e.g. $200+) in that previous post look sweet though, I may look at those when my current Sorrels need replacinh.
